Semi-submersible type lifting and disassembling platform and control method thereof

Abstract

The invention discloses a semi-submersible type lifting and disassembling platform and a control method thereof. The platform comprises a port floating body, a starboard floating body, two port stand columns, two starboard stand columns and a deck box, wherein the port floating body and the starboard floating body are each internally provided with a plurality of common water ballast tanks and a plurality of rapid water ballast tanks; the top of the rapid water ballast tank is communicated with a compressed air ballast system, column side water ballast tanks are arranged in the port stand column and the starboard stand column respectively, and the tops of the column side water ballast tanks are communicated with the compressed air ballast system. And water pump ballast systems are arranged on the common ballast water tanks, the rapid ballast water tanks and the column side ballast water tanks. The invention further discloses a control method of the platform. The safety of the platform and workers is ensured to a great extent; a set of emergency response system is established, and what is guaranteed is that when the platform encounters sudden failures in open-sea operation, platform operation command is smooth in real time, emergency rescue is rapid and accurate, and staff deal with the emergency rescue orderly and safely.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a semi-submersible lifting and dismantling platform and a control method thereof. Background technique [0002] With the deepening of our country's development of marine resources, various large-scale marine structures are increasingly needed to cope with the harsh sea conditions of the deep sea and open ocean. At the same time, some marine structures that have lost their functions also urgently need to be dismantled and recycled. [0003] CN201220358429.4 and CN201120024196.X hoisting work platforms have a structural form of symmetrical layout, and the center of gravity cranes used for hoisting operations are also symmetrically arranged on the platform deck, but when lifting and dismantling large and heavy structural parts, the platform Stability cannot be guaranteed. As a professional offshore lifting and dismantling equipment, the semi-submersible lifting and disma...

Problems solved by technology

The semi-submersible lifting platform described in the CN201110196551.6 patent is a semi-submersible lifting platform with an asymmetric structure, which has a certain effect on improving the stability of the platform, but does not involve the stability control strategy and emergency response of the platform operation. Response processing method

[0004] In addition, most of the conventional cranes balance the hull while operating, lacking the estimation and planning of the stability of the platform, and the safety of the operation is very worrying

At the same time, such platforms are often operated in the ocean, where the ocean conditions are harsh, and sudden failures such as collisions and damages are extremely prone to occur. A complete set of emergency treatment measures also needs to be established urgently
